I’ve been a fan of Homebrew Hero Yardley Beers W0JF for a long time. Here is a link to previous posts on him: http:\/\/soldersmoke.blogspot.com\/search?q=Yardley <\/a><\/b><\/div>\n
Yesterday I got a nice e-mail from Boulder Colorado about Yardley’s very early SSB rig. I’m guessing that the 4.7 MHz is a typo — it might have been 3.7 and 14 MHz. FB. Thanks Mike<\/b><\/div>\n

Yardley Beers W0JF moved to Boulder in the early 1950’s to work at the National Bureau of Standards (now NIST) laboratory. There he headed the Time and Frequency Division, which maintains the atomic clock. He later taught at the University of Colorado and Denver University.<\/b><\/div>\n
<\/b><\/div>\n
About 1955 he homebrewed what, at the time, may have been the only SSB transceiver in the world. It was built with individual transistors (no IC’s in those days) and Yardley had to grind the crystals himself for the filter. He enjoyed naming his radios and this one was “The Black Rose.”<\/b><\/div>\n
<\/b><\/div>\n
The transceiver ran at 4.7 and 14 MHz. Its 1\/2 watt output was fed to a home built amplifier. The transceiver demonstrated the practicality and benefits of SSB in a world where AM was the voice mode.<\/b><\/div>\n
<\/b><\/div>\n
In the year 2000 Yardley demonstrated this original, old SSB transceiver to the Boulder Amateur Radio Club by using it to make contacts with two club members. Attached to this e-mail are a couple of photos.<\/b><\/div>\n
